How to change touch Options in Harmony 20?

Hi! This isn’t really much of an issue, but I use a Cintiq Touch Screen 13HD, and in the program, I have to use two fingers to pan and zoom in and out. If I use just one finger it makes a stroke. I was wondering if there’s a fix to this, because in other programs I can pan with just one finger and zoom in and out with two. Thanks for your help!
